Geotech participated on a large site remediation program in 2007, completing over 40 boreholes with large diameter 8 3/4″ augers.

Four inch sparge wells were installed within contaminated zones to act as a conduit to remove large volumes of product floating on the water table. All boreholes were installed with 5 meters of well screen and grouted to the surface from the screen/riser interface.

Due to the time limitations of the program, up to four boreholes were drilled and installed, each day during a ten hour shift.

This program utilized a truck mounted B-47 drill rig, to reach depths of 20 meters.
